Title: Forming hollow bodies, such as tubes, by skew rolling
IPC: B21B19/08
Filed: 1929-02-20
Abstract: 308,783. Kocks, F. March 31, 1928, [Convention date]. Rolling tubes; skew-rolling.-Seamless hollow bodies such as tubes are produced from hollow billets by skew rolling, by a process according to which the blank has imparted to it all points of application of the rolls uniform speed of movement in the direction of the axis of the work (forward running speed) and is rotated at the same angular velocity throughout the process, the rolls being designed so that a constant ratio exists between the outer radius of the blank at any point of contact with the rolls and the distance of the axis of the blank from the point where the extension of the radius intersects the axis of the roll. The length of the blank and its cross-section of area remain constant throughout the operation. The blank 17 may be drawn over a mandrel 14 having a boss 15 by a pair of skew rolls 21, 22 having feed tapers 20, the clearance S betwen the rolls and the mandrel being gradually decreased while the blank is engaged by the tapers 20 so as to produce the axial thrust. The clearance between the rolls and the mandrel is such that the cross-sectional area of the bore of the blank is equal to or slightly larger than the corresponding area of the mandrel

Abstract: 164,115. Bollmann, H. March 1, 1920. Fats and fatty oils, purifying.-In the purification of fats and fatty oils from fatty acids, resins, mucilaginous and bitter substances, &c. by treatment in counter current with a solvent for fatty acids &c., but not for glycerides, a series of extraction vessels is used and the solvent and fatty oil are separated from each ether before passing to the next vessels. Solvents specified are methyl alcohol, ethyl alcohol, amyl alcohol, acetone, and acetic ester, diluted or not with water to ensure a sufficient difference in the specific gravity of the solvent and of the oil. When fats are treated, the temperature is maintained sufficiently high to ensure liquefaction. In the apparatus outlined in Fig. 1, rape or other oil from a reservoir 1 is passed continuously into the highest vessel 3 of a series of washing vessels 3 - - 8, and 3 times the volume of 96 per cent alcohol from a reservoir 9 into the lowest vessel 8, while the agitator works continuously. The mixture in each vessel passes continuously to the separator 11 - - 16 opposite by pipes 17, and separates into two layers, the alcoholic solution from separators 16 - - 12 passing respectively to washing vessels 7 - - 3 and that from separator 11 through a pipe 19 to a still, while the oily lower layer passes from separators 11 - - 15 respectively to washing vessels 4 - - 8 and that from separator 16 to a still for the removal of residual alcohol. A temperature of 20-30‹ C. is maintained throughout. In a modified apparatus, treatment and separation take place in the one series of vessels, no agitators being employed, but retarding means, such as Raschig rings, are used to ensure mixing and separation, and the separated oil an'd solvent flow to the next vessels through syphons. The prior use in a countercurrent process of 96 per cent alcohol and of ' acetone is referred to.
